This is the first instalment of a 2-part blog.

The current version of the KB’s digital repository system (e-Depot) doesn’t include any tools for automated file format identification yet.

Back in 2012 the KB conducted a first investigation of the suitability of the EPUB format for long-term preservation.

Shortly before Christmas, Dutch daily newspaper Trouw removed 126 articles from its website.

Eerder deze week verwijderde dagblad Trouw 126 artikelen van haar website die geschreven waren door ontslagen journalist Perdiep Ramesar.

Back in 2006, Dutch weblog Sargasso started following the activity of about 260 Dutch blogs that were active at the time, mainly by looking at the frequency of new postings.

While browsing ArchiveTeam’s File Formats Wiki earlier this week, I came across some entries I created there on Quattro Pro spreadsheets two years ago.

Earlier this week I had a discussion with some colleagues about the archiving of mobile phone and tablet apps (iPhone/Android), and, equally important, ways to provide long-term access.

Some time ago Will Palmer, Peter May and Peter Cliff of the British Library published a really interesting paper that investigated three different JPEG 2000 codecs, and their effects on image quality in response to lossy compression.

Vandaag maakte de Britse Digital Preservation Coalition de finalisten bekend die in de race zijn voor de Digital Preservation Awards 2014.

It is well-known that PDF documents can contain features that are preservation risks (e.g. see here and here).

This short tutorial shows how to take a snapshot of a web page, and save it to the Internet Archive’s Wayback Machine.

One of my first blogs here covered an evaluation of a number of format identification tools.

This blog follows up on three earlier posts about detecting preservation risks in PDF files.

My previous blog Assessing file format risks: searching for Bigfoot?

Last week someone pointed my attention to a recent iPres paper by Roman Graf and Sergiu Gordea titled “A Risk Analysis of File Formats for Preservation Planning”.

Like many other organisations that are using JPEG 2000, the KB produces two representations of most of its digitised content (newspapers, books, periodicals): a high-quality, losslessly compressed JP2 that is the archival master; a lesser-quality, lossily…

Last winter I started a first attempt at identifying preservation risks in PDF files using the Apache Preflight PDF/A validator.

It’s been more than two years now since I wrote my D-Lib paper JPEG 2000 for Long-term Preservation: JP2 as a Preservation Format.

Introduction Last year (2012) the KB released a report on the suitability of the EPUB format for archival preservation.

About a year ago, work started on packaging SCAPE tools.

The most important new feature of the recently released PDF/A-3 standard is that, unlike PDF/A-2 and PDF/A-1, it allows you to embed any file you like.

The PDF format contains various features that may make it difficult to access content that is stored in this format in the long term.

I’ve already written a number of blog posts on format validation of JP2 files.

The purpose of this post is to give a brief introduction to creating, editing and submitting format signatures (or ‘magic’ entries) for the well-known File tool.

In this blog post I’ll be dusting off some old stuff for a change.

Over the last few years, the EPUB format has gained widespread popularity in the consumer market.

Introduction In this blog post I will give a brief update of the latest jpylyzer developments.

This will be my shortest blog post ever.

A few months ago I wrote a blog post on a simple JP2 file structure checker.

As I already briefly mentioned in a previous blog post, one of the objectives of the SCAPE project is to develop an architecture that will enable large scale characterisation of digital file objects.

Over the last few weeks I’ve been working on the design of a workflow that the KB is planning to use for the migration of a collection of (mostly old) TIFF images to JP2.

As a part of the SCAPE project, I’m currently heavily involved in the evaluation of various file format identification tools.

The JPEG 2000 compression standard is steadily becoming more and more popular in the archival community.

In my presentation during the Wellcome Trust’s JPEG 2000 seminar I discussed the suitability of JPEG 2000 (and more specifically its JP2 format) for long-term preservation.
